LCD (Liquid Crystal Display):
A type of display used in digital watches and many portable computers. LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light. The benefits of DVI LCDs, in addition to those of DVI CRTs, are:

Light map:
Specific texture which simulates lighting effects according to the origin of the light source.

Lighting:
A mathematical formula to approximate the physical effect of various sources of light striking objects. Typical lighting models use light sources, the object's position & orientation and surface type.
